Figure 2.

Examples of asymmetric stationary (monopolar stable, MPS) and symmetric stationary (bipolar stable, BPS) solutions. The system evolved to these stationary states over a time course in the order of hundreds of seconds from an initially unpolarized state. (A) Concentrations as a function of arc length distance from cell tip and snapshots showing the concentration of Cdc42-GTP and GAP_II (sum of $C_{{\mathrm{GAP}}_{\mathrm{II}}}^{\mathrm{slow}}$ and $C_{{\mathrm{GAP}}_{\mathrm{II}}}^{\mathrm{fast}}$). Parameter values as in Table 1, except for $k_{\mathrm{sat}}$ = 900/μm² and $E_{\mathrm{C}}^{\mathrm{tot}}=700.$ (B) Same as panel A but for a BPS state. Parameter values same as in Table 1, except for $E_{\mathrm{C}}^{\mathrm{tot}}=1800$.
